摘要:Background Scientific workflows have been commonly used in geospatial data analysis and Cyberinfrastructure. They allow distributed geoprocessing algorithms, models, data, and sensors to be chained together to support geospatial data analysis, and environmental monitoring, and integrated environmental modelling. Results This paper presents an open source geoprocessing workflow tool, GeoJModelBuilder. It leverages open standards, Sensor Web, geoprocessing commands and services, OpenMI-compliant models together. Conclusion The implementation provides a flexible, reusable, interoperable, and user-friendly way for geoprocessing in an open environment.
